Description of the Invention: [Technical Field of the Invention] The present invention relates to a power supply system, a control device therefor, and a control method therefor, and particularly relates to generating a gas for power generation containing hydrogen from a fuel for power generation to be supplied. The power supply system, the control device thereof, and the control method thereof are supplied to the power generation unit to perform a power generation operation. [Prior Art] In recent years, with the high concern for environmental or energy issues, the company has become the mainstream fuel cell (or the power system using fuel cells) of the generation generation power system (or power generation system). . The principle of power generation of fuel cells is well known. It is the electrochemical reaction of hydrogen and oxygen. The reaction is almost no discharge of any warm gas or pollutants. The advantage is the environmental impact. (ie environmental burden) is extremely small. In addition, compared with the old power generation system (for example, a system that burns fossil fuels and generates electric energy based on thermal energy), since it can achieve extremely high power generation efficiency (energy conversion efficiency), it is developed in various industrial fields. Popular application, t is booming. Here, as a fuel for power generation for fuel cells, it is preferable to supply a high concentration of hydrogen directly, but supply the hydrogen directly to the fuel cell body. The production, storage and supply will face technical and safety issues, and more importantly, from the perspective of the economic aspects of social infrastructure, it is quite difficult to spread widely and rapidly. It can only be put into practical use from large-scale systems such as power generation equipment in specific industrial premises, or a part of special vehicle driving devices. In contrast, the power supply system that uses the fuel cell is used in a small portable electronic device (portable machine) such as a notebook 1335099 brain or a mobile phone. It is easy to start or handle it. Plus the manufacturing cost is low, and methanol is used. Liquid fuels (alcohols) of hydrocarbons such as ethanol can be said to be very realistic. In a power supply system using such a liquid fuel, a method of directly supplying a fuel for power generation (methanol or the like) to a fuel cell body, and a method of supplying the fuel for power generation to the fuel cell, and It is well known that the fuel for power generation is recombined for the supply of hydrogen obtained by recombining the components. In the fuel cell of the direct fuel supply system, since the fuel for power generation such as methanol is directly supplied to the fuel cell main body, it is not necessary to install a device such as a fuel reformer to be described later on the fuel supply path, and the fuel cell (power supply system) The structure of the fuel cell is simplified. However, in general, a fuel cell of this type has a disadvantage of low power generation efficiency (energy conversion efficiency) when compared with a fuel recombination supply method. On the other hand, in the fuel cell of the fuel recombination supply system, since the fuel for power generation such as methanol is recombined and the high-purity (high-concentration) hydrogen gas generated is supplied to the fuel cell main body, the fuel is directly supplied to the fuel cell. Compared with the fuel cell of the t mode, there is an advantage that the power generation efficiency (energy conversion efficiency) is high. Hereinafter, a power supply system of a fuel cell using a fuel recombination supply method in the prior art will be briefly described. _, = 6 is a schematic block diagram of one of the components of the fuel cell system of the fuel cell in the prior art. The " diagram represents a schematic diagram of one of the chemical reactions in the chemical reaction section of a power system using a 1335099 pool of fuel recombination. As shown in Fig. 6, the power supply system using a fuel cell in the prior art is configured to include a fuel supply unit 310 that stores or encloses a fuel for power generation such as methanol, and reconstitutes the fuel for power generation. A chemical reaction unit 320 that contains hydrogen gas for power generation, and a power generation unit portion 3300 that generates electric energy by electrochemical reaction using generated hydrogen gas and oxygen in the atmosphere.

In such a configuration, the high-concentration hydrogen gas generated by the chemical reaction unit 320 is supplied to the anode (Anode electrode) side of the power generation unit portion 330, and hydrogen ions and electrons are generated from the hydrogen gas, and the hydrogen ions are transmitted through the hydrogen ions.

然而，採用如上述般之燃料重組供給方式之燃料電池的 電源系統中，爲了使連接於該電源系統的負載可以安定的 驅動，從化學反應部320供給至發電單元部330的氫氣之 量有必要維持於一定。在此’由於化學反應部32〇中氫氣 的產生狀態（重組器3 2 2中重組反應的進行狀態），係由 包含有重組器322之化學·反應部320所設定的溫度條件所 控制’進而爲使化學反應部320所產生的氫氣之量保持一 定，有必要將化學反應部3 20設定並維持於規定的高溫狀 態，以將重組器322中重組反應的進行狀態保持於規定的 狀態。 在此’要將化學反應部3 20維持於規定的高溫狀態（一 定溫度）之方法，例如上述發電單元部3 30於發電動作（電 化學反應）時，習知的有將含有殘留未反應氫氣的廢氣、藉 由設置於靠近化學反應部320 (重組器322 )的觸媒燃燒器 (圖示省略）等的燃燒而得到的燃燒熱，或藉由電熱器（圖 示省略）等的發熱來加熱以設定於規定的高溫狀態方法等。 具體上，藉由廢氣的燃燒熱將化學反應部3 20 (重組器 3 22 )設定於規定的高溫狀態（~定溫度）的方法，係藉由 控制供給至廢氣燃燒器之廢氣或氧氣的量，而來設定廢氣 燃燒的程度（燃燒熱的產生量），以控制化學反應部320 (重組器322 )中氫氣的產生狀態（重組反應的進行狀態）。 然而，電源系統若採用上述般藉由廢氣的燃燒熱來控制 化學反應部（重組器）之溫度狀態的構成及方法，爲使發 電單元部中的發電動作更安定而可取出一定的電能（電 流），必須將氫氣的供給量設定爲比該發電動作所必需的 1335099 氫氣量及維持化學反應部（重組器）中氫氣產生動作所必 須熱能的氫氣量之總和更多》亦即，從發電單元部所排出 廢氣中的氫氣量，必須設定爲比廢氣燃燒器中被消費的量 (亦即’爲了產生重組器所必須熱能的氫氣之量）要多很 多〇However, in the power supply system of the fuel cell using the fuel recombination supply method as described above, it is necessary to supply the amount of hydrogen gas supplied from the chemical reaction unit 320 to the power generation unit unit 330 in order to enable stable driving of the load connected to the power supply system. Maintained at a certain level. Here, 'the state of hydrogen generation in the chemical reaction unit 32〇 (the state in which the recombination reaction proceeds in the recombiner 32) is controlled by the temperature condition set by the chemical reaction unit 320 including the reformer 322. In order to keep the amount of hydrogen generated by the chemical reaction unit 320 constant, it is necessary to set and maintain the chemical reaction unit 306 at a predetermined high temperature state to maintain the progress state of the recombination reaction in the reformer 322 in a predetermined state. Here, the method of maintaining the chemical reaction unit 306 in a predetermined high temperature state (constant temperature), for example, when the power generation unit unit 30 is subjected to a power generation operation (electrochemical reaction), conventionally contains residual unreacted hydrogen. Exhaust gas, combustion heat obtained by combustion of a catalyst burner (not shown) provided near the chemical reaction unit 320 (recombiner 322), or heat generated by an electric heater (not shown) Heating is set to a predetermined high temperature state method or the like. Specifically, the method of setting the chemical reaction unit 3 20 (recombiner 3 22 ) to a predetermined high temperature state (~determined temperature) by the heat of combustion of the exhaust gas is controlled by the amount of exhaust gas or oxygen supplied to the exhaust gas burner. Then, the degree of combustion of the exhaust gas (the amount of combustion heat generation) is set to control the state of generation of hydrogen in the chemical reaction unit 320 (recombiner 322) (the state in which the recombination reaction proceeds). However, in the power supply system, the configuration and method of controlling the temperature state of the chemical reaction unit (recombiner) by the heat of combustion of the exhaust gas as described above can extract a certain amount of electric energy (current) in order to make the power generation operation in the power generation unit portion more stable. ), the supply amount of hydrogen must be set to be more than the sum of the amount of 1335099 hydrogen required for the power generation operation and the amount of hydrogen required to maintain the heat energy required for the hydrogen generation operation in the chemical reaction unit (recombiner), that is, from the power generation unit. The amount of hydrogen in the exhaust gas from the part must be set to be much larger than the amount consumed in the exhaust gas burner (that is, the amount of hydrogen required to generate the heat energy required for the reformer).

Fig. 4 is a flow chart showing an example of a control method of the power supply system of the embodiment. In the power supply system of the present embodiment, the chemical reaction unit 1 is monitored by the electric heater and the thermometers HS1 to HS3 via the system control unit (temperature comparison unit, current 値 setting unit, current 値 determination unit 'voltage 値 determination unit) 170'. The temperature state in each of the components (the power generation fuel vaporizer 110' fuel reformer 120, the CO remover 130) is set to a certain temperature state suitable for each chemical reaction for generating hydrogen gas, and temperature control for maintaining the temperature state is performed. Then, if the temperature state in each member of the chemical reaction unit 100 is caused by a cause (for example, an external temperature change, a change in the output characteristic of the power generation unit portion 150) or a catalytic combustion reaction of the exhaust gas catalytic burner 140 When the characteristic is deteriorated or the like is changed, the amount of hydrogen in the exhaust gas can be controlled to be increased or decreased according to the current 値 of the output current of the electric energy taken out from the power generating unit portion 150, so that the temperature state is set and maintained constant, that is, Indicates the execution of a series of control actions. -29- 1335099 The following description is a detailed description of the execution of temperature control when the fuel reformer 1 20 that constitutes the chemical reaction unit 1 0 0 is executed. However, as will be described later, the same control method can be applied to other methods. The case of the components (the power generation fuel vaporizer 110, the C0 remover 130) is naturally not a problem.

(Detection) and sent to the system control unit 1 70 (S 1 1 1 ; thermometer measurement step). Specifically, the system control unit 170 sends the drive control signal CD to the control driver DR4, so that the electric heater and the thermometer HS2 have a small amount of current flowing through the control driver DR 4, and the voltage 此时 at this time is taken as the thermometer data. In. Then, the temperature of the fuel reformer 1200 is obtained by calculating the resistance 値 at that time based on the temperature measurement data (voltage 値). Next, it is determined whether or not the temperature (recombiner temperature) of the fuel reformer 120 coincides (same) with a preset temperature condition (set temperature) (S 1 1 2 ; temperature comparison step). If the recombiner temperature coincides with the set temperature, the process returns to the above-described step S1 1 1, and the temperature measurement operation of the fuel reformer 1 20 is continued. On the other hand, if the recombiner temperature is different from the set temperature, it is judged whether or not the recombinator temperature is higher than the set temperature (S113). When the recombinator temperature is lower than the set temperature, in order to increase the temperature, it is necessary to control the output current lout of the power generation unit portion 150 to be reduced, so that the hydrogen utilization rate in the power generation unit portion 150 is lowered, and the amount of hydrogen in the exhaust gas is increased; If the temperature of the recombiner is higher than the set temperature, in order to lower the temperature, it is necessary to control the increase of the output current i〇ut of the power generating unit portion 150, so that the utilization rate of hydrogen in the power generating unit 150 is increased, and the amount of gas in the exhaust gas is also increased. It is less than -30- 1335099. Here, the current 输出 of the output current I 〇ut taken out by the power generating unit portion 150 is limited to a range from the minimum current 値 to the maximum current 如 as will be described later. Therefore, if it is determined in step S1 13 that the recombinator temperature is lower than the set temperature, it is determined whether the current 値 from the output current lout of the power generating unit portion 150 is preset in S 1 1 4 (current 値 determination step). Minimum current 値 (set minimum current) below. On the other hand, if the recombiner temperature is higher than the set temperature, it is determined in S121 (current 値 determination step) whether or not the current 上述 of the output current Iout is above the preset maximum current 。.

於步驟S114’若從發電單兀部150的輸出電流lout之値 是在最小電流値（設定最小電流）以下時，輸出電流I〇ut 之電流値不致變爲比此値更低，因而判定該電流値過小， 則由電源系統或搭載該電源系統的電子機器所附設的報知 部（顯示器或喇叭等）來通報錯誤訊息（S 1 20 )。在此， 因應輸出電流lout之電流値過小的程度，在錯誤訊息通報 後，回到上述步驟S 1 1 1繼續燃料重組器1 20的溫度計測動 作，或將電源系統關閉（停止動作）。 另一方面，輸出電流lout之電流値若比最小電流値（設 定最小電流）大時，則控制將該輸出電流I 〇 u t之電流値降 低1級之位準（S 1 1 5 ;電流値設定步驟）。具體上，從系 統控制部170藉由將第3圖所示的被輸出至輸出控制部160 的控制信號之電流控制値，變更成從既定値降低1級之 値，而將發電單元部1 50的輸出電流lout之電流値設定爲 低1級》 如此，當重組器溫度比設定溫度低時，則減少從發電單 元部150的輸出電流lout之電流値即可控制使發電單元部 -31- 1335099 150中之氫氣消費量減低（氫氣利用率降低）。經由此，由 於可使發電單元部150所排出廢氣中含有的氫氣量增加之 故，從廢氣觸媒燃燒器1 40供給至燃料重組器1 20的熱能 會增大，而可使重組器溫度上升。In step S114', if the output current lout from the power generating unit 150 is below the minimum current 设定 (set minimum current), the current of the output current I〇ut does not become lower than this, and thus the determination is made. When the current is too small, an error message is reported by the power supply system or a notification unit (display or speaker) attached to the electronic device on which the power supply system is mounted (S 1 20 ). Here, in response to the fact that the current of the output current lout is too small, after the error message is notified, the flow returns to the above-described step S1 1 1 to continue the temperature measurement of the fuel recombiner 1 20 or to turn off the power supply system (stop operation). On the other hand, if the current 输出 of the output current lout is larger than the minimum current 设定 (set minimum current), the current 値 of the output current I 〇ut is controlled to be lowered by one level (S 1 1 5 ; current 値 setting step). Specifically, the system control unit 170 changes the current control 値 of the control signal outputted to the output control unit 160 shown in FIG. 3 to one level after the predetermined 値 is lowered, and the power generation unit unit 150 The current 値 of the output current lout is set to be lower by 1 level. Thus, when the recombiner temperature is lower than the set temperature, the current of the output current lout from the power generating unit portion 150 is reduced, and the power generating unit portion can be controlled to -31 - 1335099 The hydrogen consumption in 150 is reduced (the hydrogen utilization rate is reduced). As a result, since the amount of hydrogen contained in the exhaust gas discharged from the power generating unit portion 150 can be increased, the heat energy supplied from the exhaust gas catalytic converter 140 to the fuel reformer 120 can be increased, and the temperature of the reformer can be increased. .

其次’從發電單元部150取出的電力，被限制於後述的 最低電力値（設定最低電力）以上之範圍.，將電流値被設定 爲降低1級的發電單元部150之輸出電壓透過DC/DC轉換 器180作爲電壓資料讀入、計算發電電力（S116)，接著 判定該發電電力（計算値）是否在最低電力値以下（S丨丨7 ; 電壓値判定步驟）。 於步驟S 1 Π ’若發電電力（計算値）比最低電力値（設 定最低電力）大時’回到上述步驟S丨丨1繼續燃料重組器1 2〇 的溫度計測動作。另一方面，若發電電力（計算値）比最 低電力値（設定最低電力）小時，則判定該輸出電力係屬 過小（低電力判定），由報知器通報錯誤訊息（S 1 1 8 )， 接著控制將該輸出電流I〇ut的電流値提高1級位準 (S 1 1 9 ) °具體上’將從系統控制部〗7 〇被輸出至輸出控 制部1 6 0的控制信號之電流控制値，由上述步驟s π 5所設 定的値變更爲提高1級的値，如此也就將發電單元部15〇 的輸出電流Iou t的電流値設定爲提高丨級（電流値回到原 來的値）°之後’回到上述步驟S 1 1 1，繼續燃料重組器】20 的溫度計測動作。 又’於上述步驟S121，若輸出電流lout的電流値是在最 大電流値（設定最大電流）以上時’輸出電流I〇ut之電流 値不致變爲比此値更大，因而判定該電流値過大，則由報 -32-Next, the electric power taken out from the power generation unit unit 150 is limited to a range equal to or higher than the minimum electric power 値 (set minimum electric power) to be described later, and the current 値 is set to be lower than the output voltage of the power generation unit unit 150 of the first stage through the DC/DC. The converter 180 reads in and calculates the generated electric power as voltage data (S116), and then determines whether or not the generated electric power (calculated 値) is below the minimum electric power ( (S丨丨7; voltage 値 determination step). In step S1 Π ', if the generated electric power (calculated 値) is larger than the lowest electric power 値 (the set minimum electric power), the process returns to the above-described step S丨丨1 to continue the temperature measuring operation of the fuel recombiner 1 2〇. On the other hand, if the generated electric power (calculated 値) is smaller than the lowest electric power 値 (the set minimum electric power), it is determined that the output electric power is too small (low electric power determination), and the notifier notifies the error message (S 1 18), and then Controlling the current 値 of the output current I〇ut by one level (S 1 1 9 ) ° Specifically, the current control of the control signal output from the system control unit 7 〇 to the output control unit 160 The 设定 set by the above step s π 5 is changed to 提高 which is increased by one level, so that the current 値 of the output current Iou t of the power generating unit portion 15〇 is set to be increased to the level (the current 値 returns to the original 値). After 'return to the above step S 1 1 1, continue the fuel recombiner】 20 thermometer measurement action. Further, in the above step S121, if the current 値 of the output current lout is greater than the maximum current 设定 (set maximum current), the current of the output current I〇ut does not become larger than this, and thus the current is too large. , by the newspaper -32-

In response to the excessive current of the output current I 〇 u t, the error returns to the above step S 1 1 1 to continue the temperature of the fuel recombiner 丨 20, or to turn off the power system (stop operation). On the other hand, when the current 输出 of the output current lout is smaller than the maximum current constant current, the system control unit 1 7 increases the current control 値 of the control signal output from the control unit 1 60 from the predetermined 値 level 1 The 値' is used to control the level of the current level of the output current I 〇ut (S 1 2 2 ; current 値 setting step). Thus, when the recombiner temperature is higher than the set temperature, the current 値 from the output current lout of the unit portion 150 is increased to control the hydrogen consumption in the power generation 150 (the hydrogen utilization rate rises). The amount of hydrogen contained in the exhaust gas discharged from the power generation unit portion 150 can be reduced from the supply of the exhaust gas catalytic converter 140 to the fuel reformer 1 20, and the temperature of the reformer can be lowered. Next, the output voltage of the power generation unit unit 150 is set to a range equal to or higher than the minimum voltage 値 (set minimum voltage), and the power is set to increase the output voltage of the power generation unit unit 150 of the first stage through the converter 180 as voltage data. After reading (S 1 23 ), it is determined whether 値 (read 値) is at the lowest voltage 値 (set the minimum voltage (S124; voltage 値 determination step). In step S 1 24, if the voltage 値 (read 値) is the lowest ratio When the voltage 値 minimum voltage is large, return to the above-described step S 1 1 1 to continue the thermometer measurement operation of the fuel weight 糸i. On the other hand, if the voltage 値 (read 値) voltage 値 (the set minimum voltage) is low, it is determined that the voltage 値 is here, and the measurement is notified (the output is changed to increase the power generation unit unit, The reduced thermal energy is below the DC/DC voltage by the flow described later (the setting 120 is lower than the lowest is -33-1335099 (low voltage determination), and the notification unit notifies the error message (S 1 2 5 ), and then The current control 输出 outputted from the system control unit 170 to the control signal of the output control unit 1 60 is changed to 降低 which is reduced by one level by the 设定 set in the above step S 1 22, so that the current due to the electric energy is also 値(Output current lout) is controlled to decrease the level 1 level (S 1 2 6 ). Thereafter, returning to the above step S 1 1 1, the thermometer measuring operation of the fuel recombiner 1 20 is continued.

再者，於上述步驟S 1 20及S 1 27中，在錯誤訊息通報後， 要回到步驟S 1 1 1繼續溫度計測動作之時，由於單之如此重 組器溫度不會迅速變化至最佳狀態，故例如藉由控制流體 閥門VL3以調整供氧量至廢氣觸媒燃燒器1 40、或控制流 體閥門VL1而間接調整供給至燃料重組器120的燃料氣體 量，使燃料重組器1 20的溫度狀態變化至最佳狀態後，再 繼續步驟S 1 1 1的溫度計測動作亦可。 其次，有關適用於本實施形態之電源系統的發電單元部 之發電特性，其與上述控制方法的關係加以具體說明。 第5圖係表示適用於本實施形態之電源系統的發電單元 部之輸出特性（發電特性）之圖。 在上述電源系統的控制方法（化學反應部的溫度控制） 中，從發電單元部150取出電能的控制範圍係有限度的， 通常’以發電動作的範圍內執行控制，以使氫氣利用率在 又’於本實施形態之電源系統，如上述，其構成係在將 由發電單元部150輸出的電能供給至DC/DC轉換器180, 經既定的一定電壓轉換後，作爲負載驅動電力而供給至負 載。 -34- 1335099 於如此的電源系統，如第5圖所示’當因應於發電單元 部1 5 0所取出電能的電流値（輸出電流）增加時，發電單 元部1 50的電壓値（輸出電壓）顯示有緩慢降低的傾向（參照 測定電壓値的特性曲線）。 又，根據上述電壓値所計算的電力値（發電電力），若 將電流値（輸出電流）增加時，顯示其呈略直線性增加的Furthermore, in the above steps S 1 20 and S 1 27, after the error message is notified, when returning to step S1 1 1 to continue the temperature measurement operation, since the temperature of the recombiner does not change rapidly to the optimum State, so that the amount of fuel gas supplied to the fuel reformer 120 is indirectly adjusted by, for example, controlling the fluid valve VL3 to adjust the oxygen supply amount to the exhaust gas catalytic converter 140 or the control fluid valve VL1, so that the fuel reformer 1 20 After the temperature state changes to the optimum state, the temperature measurement operation of step S1 1 1 may be continued. Next, the relationship between the power generation characteristics of the power generating unit portion applied to the power supply system of the present embodiment and the above control method will be specifically described. Fig. 5 is a view showing the output characteristics (power generation characteristics) of the power generating unit portion applied to the power supply system of the present embodiment. In the above-described control method of the power supply system (temperature control of the chemical reaction unit), the control range for extracting electric energy from the power generation unit unit 150 is limited, and usually control is performed within the range of the power generation operation so that the hydrogen utilization rate is again In the power supply system of the present embodiment, as described above, the electric power output from the power generation unit unit 150 is supplied to the DC/DC converter 180, and after being converted by a predetermined constant voltage, it is supplied as load drive power to the load. -34- 1335099 In such a power supply system, as shown in Fig. 5, when the current 値 (output current) due to the electric power taken out by the power generating unit portion 150 is increased, the voltage 发电 (output voltage) of the power generating unit portion 150 ) shows a tendency to slowly decrease (refer to the characteristic curve of the measured voltage )). Further, when the current 値 (output current) is increased based on the electric power 发电 (generated electric power) calculated by the voltage 上述, it is slightly increased linearly.

傾向，在發電單元部150的氫氣利用率介於75 % ~95 %具有 控制範圍（發電單元部1 50的通常控制範圍）內最大値（參 照測定電力値的特性曲線）。 在此，已如第4圖的流程圖及第5圖的輸出特性圖所示， 所謂設定最小電流 '設定最大電流、設定最低電力及設定 最低電壓等，乃係不使發電單元的輸出急劇下降，或不使 發電單元損傷、劣化，而對應於發電單元部150之安定動 作範圍限度的一些設定値。 如此’上述電源系統的控制方法（一連串的溫度控制動 作）’係於發電單元部150的氫氣利用率介於75 % ~95 %之 控制範圍（通常控制範圍）內，且在發電單元的安定動作範 圍內，得以良好地被實現。 此處’電源系統雖被設計爲正常動作時在上述範圍內有 良好的動作，但發電單元部150的輸出電壓、或根據此而 計算出來的電力値（發電電力），若發生低於上述設定最 低電壓、或設定最低電力以下現象時，即意味著電源系統 有某種的異常（故障）產生，DC/DC轉換器180也會跳脫 正常動作範圍，由電源系統所驅動的負載（電子機器等） 也就不能維持正常的動作。發生此種狀態時，在通報錯誤 -35· 1335099 信息（顯示等）後’如上述’可使燃料重組器丨2 〇的溫度 狀態變化到最佳狀態後’繼續燃料重組器丨2〇的溫度計測 動作，或將電源系統關閉（停止動作）。 如以上說明，於本實施形態之電源系統的控制方法中， 燃料重組器1 2 0的溫度若比設定溫度高時，則控制使發電 單元部1 5 0的輸出電流之·電流値增加、使發電單元部1 5 〇 的氫氣消費量增加，也使氫氣利用率提高。亦即，伴隨溫 度的上升’燃料重組器1 2 0中的重組反應會被促進，被產 生的氫氣量會比發電單元部150及廢氣觸媒燃燒器140消 費的氫氣量更多’於廢氣中發生氫氣量增加的現象時，藉 由使發電單元部150中的氫氣利用率提高，則該等廢氣中 的氫氣量即會相對減少，由廢氣觸媒燃燒器140所產生的 ' 熱能也會減低，故而可控制使燃料重組器1 2 0的溫度降低。There is a tendency that the hydrogen utilization rate of the power generation unit portion 150 is between 75% and 95% with a control range (normal control range of the power generation unit portion 156) (the characteristic curve of the measured power 値). Here, as shown in the flowchart of FIG. 4 and the output characteristic diagram of FIG. 5, the setting of the minimum current 'setting the maximum current, setting the minimum power, setting the minimum voltage, etc., does not cause the output of the power generating unit to drop sharply. Or, the power generating unit is not damaged or deteriorated, and some settings corresponding to the limit of the operating range of the power generating unit portion 150 are set. Thus, the above-described control method of the power supply system (a series of temperature control operations) is performed in the control range (normal control range) in which the hydrogen utilization rate of the power generation unit portion 150 is between 75% and 95%, and the stabilization operation of the power generation unit is performed. Within the scope, it has been well implemented. Here, the power supply system is designed to operate well in the above range during normal operation, but the output voltage of the power generation unit unit 150 or the power 値 (power generation power) calculated therefrom is lower than the above setting. When the minimum voltage or the minimum power is set, it means that the power system has some abnormality (fault), and the DC/DC converter 180 will also trip out of the normal operating range, and the load driven by the power system (electronic machine) Etc.) It is impossible to maintain normal movements. When this state occurs, after the error -35· 1335099 information (display, etc.) is notified, the temperature of the fuel recombiner 继续2〇 can be continued after the temperature state of the fuel reformer 丨2 变化 is changed to the optimum state as described above. Measure the action or turn the power system off (stop action). As described above, in the control method of the power supply system of the present embodiment, when the temperature of the fuel recombiner 1 20 is higher than the set temperature, the current/current of the output current of the power generation unit unit 150 is controlled to be increased. The increase in hydrogen consumption in the power generation unit unit 1 5 , also increases the hydrogen utilization rate. That is, as the temperature rises, the recombination reaction in the fuel reformer 120 will be promoted, and the amount of hydrogen generated will be more than the amount of hydrogen consumed by the power generation unit portion 150 and the exhaust gas catalytic converter 140 in the exhaust gas. When the amount of hydrogen gas increases, the amount of hydrogen in the exhaust gas is relatively reduced by increasing the hydrogen utilization rate in the power generating unit portion 150, and the heat energy generated by the exhaust gas catalytic converter 140 is also reduced. Therefore, it is possible to control the temperature of the fuel reformer 120 to be lowered.

另一方面，燃料重組器1 20的溫度若比設定溫度低時， 則控制使發電單元部1 5 0的輸出電流之電流値減少、使發 電單元部1 5 0的氫氣消費量減低，也使氫氣利用率下降。 亦即，伴隨溫度的下降，燃料重組器1 20中的重組反應會 被抑制，被產生的氫氣量會比發電單元部1 5 0及廢氣觸媒 燃燒器1 40消費的氫氣量更少，於廢氣中發生氫氣量減少 的現象時，藉由使發電單元部150中的氫氣利用率降低， 則該等廢氣中的氫氣量即會相對增加，由廢氣觸媒燃燒器 1 40所產生的熱能也會增大，故而可控制使燃料重組器1 20 的溫度上升。 如此，藉由因應化學反應部1 00 (燃料重組器1 20 )的溫 度而來適當地調整發電單元部150的氫氣利用率’對於由 -36- 1335099 該發電單元部150對廢氣觸媒燃燒器140供給的廢氣中含 有的氫氣量可相對予以增減，由於可控制僅供給廢氣觸媒 燃燒器140熱能產生所必要的氫氣量，故可使廢氣中的氫 氣完全被消費，進而可使電源系統的發電效率提高。特別 是在本發明之電源系統的控制方法中，由於產生電能的發On the other hand, when the temperature of the fuel reformer 190 is lower than the set temperature, the current 値 of the output current of the power generation unit unit 150 is controlled to be reduced, and the hydrogen consumption of the power generation unit unit 150 is also reduced. Hydrogen utilization rate has decreased. That is, as the temperature decreases, the recombination reaction in the fuel reformer 1 20 is suppressed, and the amount of hydrogen generated is less than the amount of hydrogen consumed by the power generation unit portion 150 and the exhaust gas catalytic converter 1 40. When the amount of hydrogen gas is reduced in the exhaust gas, the amount of hydrogen in the exhaust gas is relatively increased by lowering the hydrogen utilization rate in the power generating unit portion 150, and the heat energy generated by the exhaust gas catalytic converter 140 is also increased. This will increase, so that the temperature of the fuel reformer 1 20 can be controlled to rise. Thus, the hydrogen utilization rate of the power generation unit portion 150 is appropriately adjusted by the temperature of the chemical reaction portion 100 (the fuel reformer 1 20). For the power generation unit portion 150 to the exhaust gas catalytic burner by -36-1335099 The amount of hydrogen contained in the exhaust gas supplied by 140 can be relatively increased or decreased. Since the amount of hydrogen necessary for generating only the heat energy generated by the exhaust gas catalytic converter 140 can be controlled, the hydrogen in the exhaust gas can be completely consumed, thereby enabling the power supply system. The power generation efficiency is improved. Particularly in the control method of the power supply system of the present invention, since the generation of electric energy is generated

Therefore, the driving state of the entire power supply system can be optimized. , can further improve the efficiency of power generation. Further, in the power supply system of the present embodiment, the power generation operation of the power generation unit unit 150 (that is, the hydrogen gas utilization rate) and the amount of hydrogen gas supplied to the exhaust gas of the exhaust gas catalytic converter 140 are performed. By controlling the amount of gas directly supplied by the chemical reaction unit 100 (fuel reformer 1 2 〇), it is not necessary to provide a valve or a flow meter or the like to control the supply of the exhaust gas to the exhaust gas catalytic burner 140 as in the prior art. . Further, since the gas (exhaust gas) discharged from the exhaust gas catalytic converter 140 contains almost no hydrogen gas, it is not necessary to provide a residual gas burner as in the prior art. Accordingly, the present invention can simplify the miniaturization of the power supply system or the simplification of the structure, as well as the reduction in the cost of the product. In addition, the control method of the power supply system described above monitors the temperature state of the fuel reformer constituting the chemical reaction unit 1 by the electric heater and the thermometer HS 2, and adjusts the supply to the exhaust gas by the temperature. The amount of hydrogen in the exhaust gas of the combustor 140 has been described; however, the present invention is not limited thereto, and for example, in a power supply system in a stable operating state, the components constituting the chemical reaction unit 1 (the power generating fuel vaporizer 1 1 〇 The temperature state of the fuel reformer 1 2 〇 and the C 〇 remover 130) is set and maintained by the thermal energy supplied by the exhaust gas catalytic burner 14 - -37 - 1335099, and may also constitute a chemical reaction unit. At least a few of the fuel-generating fuel vaporizer 1 10, the fuel reformer 120, and the CO remover 130 are monitored by the electric heater and the thermometers HS1, HS2, and HS3, and then adjusted according to the temperature.
